FILE: file_samples_authentication_async.py
DESCRIPTION:
These samples demonstrate authenticating a client via a connection string,
shared access key, or by generating a sas token with which the returned signature
can be used with the credential parameter of any ShareServiceClient,
ShareClient, ShareDirectoryClient, or ShareFileClient.
USAGE:
python file_samples_authentication_async.py
Set the environment variables with your own values before running the sample:
1) AZURE_STORAGE_CONNECTION_STRING - the connection string to your storage account
2) AZURE_STORAGE_ACCOUNT_URL - the queue service account URL
3) AZURE_STORAGE_ACCOUNT_NAME - the name of the storage account
4) AZURE_STORAGE_ACCESS_KEY - the storage account access key
